5. Assembling Sidewall Sheets
32 PNEG-4030 40 Series 27' and 30' Diameter Bins
Caulking Detail for Standard (Non-Laminated) Sheets
To keep out moisture from overlapping the sheets, it is necessary to apply caulk to each sheet prior
to installing.
NOTE: Always assemble the sidewall sheets with the overlap in the same direction.
1. Apply a strip of caulk near the outside edge of the outer sheet and between the outer two (2) rows
of bolts (A), then apply a strip of caulk 10" (25.4 cm) long along the horizontal seams (B), as shown
in
Figure 5A .

2. Before bolting the next ring into place, apply one 10" strip of caulk (C) on the front of the underlapped
sheet at each joint.
3. Also, place a 10" (25.4 cm) strip of caulk (D) along the lower horizontal edge of the lapping
sheet at every vertical seam. This will fill the space that occurs between the holes caused by the
overlapping sheets.
